Whileitisrecommendedtofollowtheinstructionsprovidedintheparagraphon
stabilisingthemachine,forvariousreasonsoneofthestabilisersmaylosecontact
withtheground,thuschangingtheangleofthemachine orcausingafootplate
toli
ftfromtheground.Ifthisoccurswhenthemachineisataheight,movements
arestoppedanddisabledimmediately.Torestoreoperationoftheplatform(close
theaerialpartandthenstabilisethemachineagain)theelectricalemergencyde‐
scentfunctioncanbe used,whichinvolvesonlythere
turnoftheaerialpart.Ifthis
isnotpossibleduetothepresenceofobjectsthatinterferewiththeoperation,per‐
sonnelonthegroundcanallowtheoperatorinthebaskettoclosethemachine.
Theoperatorsonthegroundcanbypassthemachineʹssafetydevicesand allow
theoper
atorinthebaskettoclosethemachineorallowthemanualoperationsas
describedinthepreviouspa ragraphs,inordertobringtheoperatorbacktothe
ground.
Proceedasfollows:
